Project Overview
New Wastewater Treatment Plant
The New Lions Gate Wastewater Treatment Plant constructed in North Shore on a 8.6-acres (3.5-hectare) site will provide secondary treatment to approximately 200,000 residents.
Why Trust Anyone Else?
Acciona Design Build teamed with EFCO to provide formwork and engineering support for the 111′-9 1/2″ (34.1 m) tall digesters. The twin 70′-2 1/2″ (21.4 m) diameter digesters were poured in 10 uninterrupted, full circumference lifts with integrated hopper pours on the third and fourth lifts.
Customer Benefits
Curved Formwork Panel Can Be Cycled Numerous Times
The REDI-RADIUS panel is a complete forming unit and is delivered flat to the jobsite. With a simple shaping table built on site, each panel can be shaped to the specified radius.
Fixture Built Precision Formwork
EFCO’s tried and true EFCO Quick Bolt connection ensures excellent panel joint alignment, eliminating formwork offsets. Numerous pipe penetrations were incorporated into the formwork plan, leading to a successful engineered forming design.
360-degree Access On Both The Inner And Outer Sets Of Formwork
EFCO’s GUIDED RAIL SYSTEM®, with its form roll back mechanism, was used on the outer walls, and conventional jump brackets were used on the inner walls.
Safe And Timely Formwork Cycling
With the use of the GUIDED RAIL SYSTEM, the support system never becomes detached from the structure.
Shoring and Engineering Support
Using EFCO’s renowned steel SUPER STUD® system as the support shoring, engineering was able to provide a conical design that followed the geometry of the hopper soffit.
